The groove can realize stable sliding connection with the inclined ends on both sides of the bottom of the connecting frame 1153, and correspondingly, a lock shaft 1156 is fixedly connected to the side of the slider 1155 for quick plug-in locking, and lock holes 1157 are symmetrically opened on the left and right sides of the upper end of the stirring rod 4 and connected to the lock shafts 1156 on both sides, a guide rod 1158 is transversely installed at the lower end of the docking shaft 1151 and slidably connected to the bottom of the sliders 1155 on both sides, and a reset spring 1159 is installed on the outer side of the middle part of the guide rod 1158, and the left and right sides of the reset spring 1159 are respectively connected to the bottom of the sliders 1155 on both sides.

[0040] The lifting structure 1122 includes a pressing plate 11221 connected to the lower end of the cylinder 1123, a pressing shaft 11222 vertically fastened to the left side of the lower end of the pressing plate 11221, and the position of the pressing shaft 11222 is opposite to the plug-in shaft 1152, a connecting shaft 11223 vertically plugged into the right side of the lower end of the pressing plate 11221, and a connecting pipe 11224 sleeved on the outer side of the connecting shaft 11223, and the connecting shaft 11223 and the connecting pipe 11224 form a telescopic pipe structure, which is symmetrically installed on both sides of the inside of the connecting pipe 11224 and connected to the bottom of the connecting shaft 11223. The springs 11225 connected on both sides can provide a certain downward pressure space to squeeze or move away the plug-in shaft 1152 when the pressure plate 11221 moves downward or upward, and dock with the protective shell 11226 at the lower end of the connecting pipe 11224, and one side of the protective shell 11226 is inserted into the hollow space opened at the upper end of the connecting block 111, and the protective shell 11226 is equipped with a driving wheel 11214, a transmission belt 11215 and a driven wheel 11216, and the protective shell 11226 is rotatably connected to the upper end of the connecting sleeve 11213 on the side close to the driven wheel 11216.

[0041] Specifically, when the raw materials are to be fully stirred and mixed, the raw materials can be poured in from the feed port 3 provided on the left side of the upper end of the top cover 2. At this time, the servo motor 113 provided on the rear side of the running bracket 10 can be used to make the servo motor 113 realize the circumferential rotation of the connecting block 111 connected to the output end. As the connecting block 111 rotates, the connecting block 111 connected to the upper and lower ends of the reactor body 1 through the quick connector 115 and the adjustable receiving assembly 114 can realize the circumferential rotation of the reactor body 1 as a whole. At the same time, when the connecting block 111 rotates, the rotation of the transmission bevel gear 11212 provided inside the upper end will be realized, so that the transmission bevel gear 11212 can rotate along the bevel gear plate 11211 fastened to the middle part of the front side of the bracket 10, so that the transmission bevel gear 11212 can rotate with the bevel gear plate 11211 1 is meshed with the outer tooth angle to realize self-rotation activity. In this way, the connecting sleeve 11213 connected to the outer side of the upper end of the transmission bevel gear 11212 can realize the rotation of the driving wheel 11214 connected to the outside, and the rotating driving wheel 11214 can cooperate with the transmission belt 11215 provided on the outside to realize the synchronous rotation of the driven wheel 11216 connected to the front side. Therefore, the quick connector 115 connected to the middle of the driven wheel 11216 can rotate synchronously to drive the stirring rod 4 quickly connected to the bottom to rotate, so that the stirring rod 4 stirs and mixes the raw materials inside the reactor body 1. In this way, the raw materials inside the reactor body 1 can be stirred and mixed with the circumferential rotation of the reactor body 1 and the rotation of the stirring rod 4, so as to achieve efficient stirring and mixing, thereby avoiding the problem of insufficient mixing of the raw materials, resulting in poor quality of the soil loosening agent prepared subsequently; Secondly, when the rotary stirring structure 1121 and the stirring rod 4 need to be disassembled, the cylinder 1123 provided at the upper end of the connecting block 111 can be driven to make the cylinder 1123 realize the upward movement of the bottom contacting pressure plate 11221, so that the pressing shaft 11222 and the connecting shaft 11223, which are connected to the left and right sides of the bottom of the pressing plate 11221, can be moved upward, and the pressing shaft 11222 moves upward, which can release the offset effect of the plug-in shaft 1152 provided at the middle part of the upper end of the docking shaft 1151, so that the plug-in shaft 1152 and the connecting shaft 11223 can be connected. The compression spring 1154 between the frames 1153 rebounds to automatically pull the plug-in shaft 1152 and the connecting frame 1153 upward. At the same time, as the connecting frame 1153 moves upward and downward, the sliders 1155 docked on both sides of the bottom of the connecting frame 1153 can move horizontally relative to each other through the elastic pull-back effect of the return spring 1159 provided on the outer side of the middle of the guide rod 1158. In this way, the locking shafts 1156 provided in the middle of the side edges of the sliders 1155 on both sides will simultaneously move out of the locking holes 1157 opened on both sides of the upper end of the stirring rod 4 to achieve At the same time, when the connecting shaft 11223 moves upward along the inside of the connecting tube 11224, the pressing plate 11221 can be moved upward as a whole in advance, so that when the abutment state between the pressing shaft 11222 and the plug-in shaft 1152 is released, the protective shell 11226 can be in a pre-static state, and when the connecting shaft 11223 moves upward to the upper end of the connecting tube 11224, the connecting shaft 11223 can realize the overall upward pull of the protective shell 11226, so that the protective shell 11226 moves upward along the hollow part of the upper end of the connecting block 111, so as to realize The rotating stirring structure 1121 is now separated from the stirring rod 4, ensuring that when the subsequent reactor body 1 is tilted and opened with the adjustable receiving assembly 114, it is not easy to cause an obstruction problem. At the same time, when the protective shell 11226 moves up, the connecting sleeve 11213 connected to the inner side of the protective shell 11226 can move up along the middle part of the upper end of the transmission bevel gear 11212 to ensure that the driving wheel 11214 does not need to be disassembled from the upper end of the transmission bevel gear 11212, and the rotating stirring structure 1121 can be quickly disassembled and separated from the upper end of the stirring rod 4. When the upper end of the stirring rod 4 is subsequently re-joined with the rotating stirring structure 1121, the cylinder 1123 can push the pressing plate 11221 downward to move the pressing shaft 11222 and the connecting shaft 11223 downward, and the elastic force of the spring 11225 between the connecting shaft 11223 and the connecting tube 11224 can offset the pressing plate 11221 and the protective shell 11226 simultaneously. When the protective shell 11226 moves down to the quick-connect position, the pressing shaft 11222 can be pre-joined with the upper end of the plug-in shaft 1152. At this time, the cylinder 1123 pushes the pressing plate 11221 downward again to insert the connecting shaft 11223 into the connecting tube 11224. In this way, the pressing shaft 11222 can be moved downward at the same time. The plug-in shaft 1152 is pushed downward to make the plug-in shaft 1152 squeeze the connecting frame 1153 connected to the bottom. As the connecting frame 1153 moves downward, the sliders 1155 docked on both sides of the bottom of the connecting frame 1153 can be squeezed and move left and right in opposite directions. Therefore, the locking shafts 1156 arranged at the outer ends of the sliders 1155 on both sides can be correspondingly inserted into the locking holes 1157 opened on both sides of the upper end of the stirring rod 4 to realize rapid docking and ensure that the rotating stirring structure 1121 is quickly connected to the stirring rod 4, so that the rotating stirring structure 1121 can perform a circular rotation of the reactor body 1. At the same time, the stirring rod 4 can also be driven at the same time to fully stir and mix the raw materials inside the reactor body 1.
